Be it known that I, DARIQ4 BUCcIooNE, a

" Subject ofthe King 'of Italy, residing ai Canonsburg, in the county of Washington 'and State of Pennsylvania, have invented certain new and usefuly yImprovements in Feeding. Mechanisms for Tinning Machines,

of which the following isv a specification.

This invention'relates to .certain new and useful improvements 1n feeding mechanisms for tinning machines and `relates particu- The principal object of the inventionv is to provide an improved liquid tank adapted toin lrapid succession from a pack orV pileto the tinning .pot of lavtinning machine.

hold ythe pack lof plates` and provided with means for elevating the plates one at a time out of thesame to an elevated position, the tinning machine being equipped with overhead feeding mechanism to receive the plates thus elevated and deliver the same to the tinning pot, theV elevating means and -feding means being adapted for intercon-4 nection when the device is in operation and being capable of disconnection for permitting a newfilled tank to be brought into place, and ,thefeeding means bein `exten- .sible' and engageable with the e evating `mean s,.a'nd means being associated with the extensiblefeeding means for automatically keeping the elevating means engaged with itheplates as theyl arefed from the tank.'

Another. object ofthe invention is to geni' f eral1y`improve devices of this character so as to,elevate and deliverplates from, the

tank Vto the tinning potin a most expeditious and practical manner and with the necessity of little Vattention to the apparatus as possible" other objects will become apparent as the 'Y 'I nature of the'invention is better "understood,

' VReferring in detail tothe drawings, 5 in dicates a liquid containing tank or feed box designed to hold in addition to the liquid,

Va pack of plates 6, the plates being disposed vertically as shown clearly in Fig. 1, and

the tank 5 being' preferably of multiple 'v1 ded with The flux-box ofthe tinning machine is indicated at 9, and the metal containing compartment of the tinning pot is designated` by the numeral 10, this flux-box being proplates are to be delivered. a

Locatedover the tank 5 is a feeding mechanism for delivering the plates to thefluxbox as they are elevated from the tank. This mechanism and its supporting and driving.

the usual delivery mechanism including the,

cooperating friction rolls 17 and 18.

A bracket 19 rests upon each end of the rontwallfof the tinning machine, and the rear-ends of a pair of rods 20 are fixed in eachof said brackets, the rods 20 being disposed in a horizontal position slightly below the shaft 11 and being fixed to a suitably supporting block' 21 at its other end below the bearing of the shaft 11 in said block as at 1-2. The block 21 rests on a cleat 21 fixed to a wall of the building.

Each bracket 19 has an end portion of a transverse shaft 22 journaled therein, and a plurality of friction wheels 23 are fixed at intervals upon this shaft, while a worm gear 24 is secured upon one end of the latter so as to mesh with the worm portion 25 of the power shaft 11 for causing rotation of this shaft 22 and its friction wheels 23. Another shaft 26 is journaled in vertically adjustable bearings carried by the brackets 19 above the shaft 22, and said shaft 26 is also provided with a plurality of friction wheels 27, each wheel' 27 bei one friction wieel 23 of the shaft 22, and the wheels 23 and 27 beingdisposed in pairs, one pair for the sheets from each compartment of the tank 5 so that the rollers of the pairs engage the upper, and under surfaces of the sheets along the side edges of the latter when said sheets or tins are fed to the flux-box. A shaft hanger 28 is slidably mounted yupon each rod 20, and the ends of another transverse shaft 29 "are journaled in the-,lower'portions of saidshaft hangers 28,"while a further transverse shaft 30 is journaledA in vertically movable bearings provided in theshaft hangers 28 above the shaft 29. lRollers 31 and`32zsimilar to the wheels or rollers '23 `and ,27(and similarly disposed, are. respectively fixed upon the shafts 29 and 30. A- still further shaft hanger 33. is slidably mounted upon each guides 8' between which theperipherally engaged with pair-of rods 20 adjacent the shaft hanger .28,y and this shaft hanger 33 has a pair of superpos'ed sh'afts respectively indicated at 34 and` 35 journaled therein similar to the .provision of the shafts29 andy 30 in the shaft hanger 28; -The shafts 34 land 35 are respec-` tivelyprovide'd with friction wheels 36 and 37 disposed and related in a manner similar to lthat described with respect to the wheels 23 and 27. The shafts 22, 29 and 34 are respectively vprovided with worm gears 15, 38

and 39 meshing with the worm' portion 25 of the shaft 11 for driving the rolls or wheels of said shafts 22, 29 and 34. It is to vbe un-` derstood that the rollers`23 and 27, 31 and 32, and 36 and 37 are so related as to permit the passage of the plates -therebetween with incident friction sufficient to feed the plates ata uniform speed, which friction may be regulated by the adjustmentof the shafts 26, 30V and 35 toward or away from the shafts 22, 29and 34.

Extensible frames or intermediateV hangers for the shafts of the feeding mechanism, are provided, and they include lower frames each embodylng a pair of slidably connected members or plates 40 and 41 which are provided with longitudinal slots 16 and interengaging collars 42,and 42 respectively integral with the members'40 and 4l and slidable on shafts 22 and 34. As shown in Fig.l 4, the shaft 29 passes through the slot of each lower frame, while the shafts 22l and 34 are removably journaled in the ends of the latter. Similarly, each upper frame comprises slidably connected plates or members 43 and 44 which are slotted and connected ina similar manner, the shaft 30 bein through the slotof each upper rame, and `the shafts 26 and 35 being journaled in the members 43 and'44 respectlvely. The free ends of the plates 43 and 44 of each upper frame are downwardly curved to provide guides 45 and 46 vrespectively which are adapted to lead the plates from the wheels 23 and 27 to the rollers 14 and to lead ,the plates between the rollers 36 and 37 from the elevating means, which will be presently de scribed, and which is provided in the combracket 19 and the shaftv hanger 28 is ob- 'f tained so `as to keep the spaces between these elements as nearly equaly as possible, the necessity for which will be apparent.

The movement of the shaft hanger 33 disposed away from the bracket l19 is accomplished u preferably by means of aweight 48 suspended upon one end ofalexible member 49 which passes around a pulley 50 fixed to the right hand end of one .of the rods 20, and

, mechanism generally denoted at 53 may be which is as at 51 to the arm 52 of the 'shaft hanger 33. A suitableholsting provided lfor raising the weight 48 so as to permit retraction of the 'parts to their normal startingposition as shown in Fig. 1, and this movement of the shaftl hangers is provided lso as to cause the elevating mechanism of .each tank compartment to always keep into engagement with the plates 6, said elevating mechanisms each comprising carriages 54 movable transversely of the tank compartment and engageable by a depending abutment or Varm 55 for imparting movement to the carriages 54 as allowedby the successive removal of the plates 6 and as inluenced by the weight 48 and its connection with the shaft hanger 33. The carriages 54 l' nism -is composed of a p air of carriages54, and adjacent pairs of said carriages ma bei l plates 62 rigidly connected' in rame disposed in slightly are mounted for movement transversely of the tank 5, two of said carriages being disposed upon the u per edges of the end Walls of said tank, andpthe others beinfg similarly disposed upon the upper edges o tions 7, anti-friction rollers 56 being provided on the carriages for ridin upon the upper edges of the end Walls anv the partitionsof the tank 5 so as toinsure this movement freely under the action of the weight 48. Each carriage embodies an uppersheet metal frame of substantially C -sha in top lan as seen in Fig. 3 with the en of the spaced. relation to provide a slot 57' throug which the edges of the plates 6 move-when being elevated and by means of which the said plates vare directed between suitable friction rollers 58 and 59 which are respectively secured at intervals upon the transverse shafts 60 andy ranged in the same horizontal plane an side by side, while theshaft 61'is adjustable to and from the shaft so astopermit ob.

taining VVof the proper relation between the friction wheels 58 and 59. friction wheels 58 and 59 are disposed upon the shafts 60A and 61 in substantially the same relation as hereinbefore described with respect to the friction rollers 23and 2 7.

Eachv sheet feeding or elevating mechav integrall =.fori ned or' A rigidly eonnec as seen in yig, 2. The plairofcarriages for eachcompartment oft e tank 'suppo'rtsa depending frame composed of a pair of 'silde re ation in any suitabllmanneran provided 4with a transverse connectingplate63 around which 1a pairof endless chains 64 pam, said chains bein arranged, one adjacent plate 62 an each engaging a sprocket Wheel' 65 -at thelower ends of the plates and a simiI lar sprocket wheel 66 at the upper ,ends

the parti-` thereof, a shaft being suitably rotatably mounted in the lower ends of the plates 62 and havi 4the sprockets 65 fixed thereon, and a simi ar shaft being rotatably mounted in the upper members of the carriages 54 with the sprockets 66 secured thereon. The chains 64 are connected by a transverse friction member or pad 67 which is disposed so as to engage the outer plates of the piles of plates when said friction members 67 are moved in an orbital path by travelling with the chains 64.

The shaft 6() is preferably driven from the shaft 34 by means of a sprocket gearing includin a sprocket chain 68, and this rotation'of s aft 60 isl transmitted to the shaft which carries the sprockets 66 by means of a chain 69 which may be passed around the desired alined ones of the sprocket wheels 70 upon the latter shaft and the sprocket wheels 71 upon'the shaft 60. As shown, the sprocket wheels 70 gradually decrease in size from left to right,` while the sprocket wheels 71l increase in size in the same direction so that by changing the chain 69`to different pairs of these sprockets, the chain 64 of the sheet elevating means may be driven at different speeds according the chain 69 ma be removed andl when this .is done the over' ead feeding' means may be 51 in the shaft 13, and the tank 5 Vmay be then taken awa so as to brin vinto place another tank w ich is filled Iwith `plates 6 after the first tank hasbeen emptied. It will also be noted that when the abutment orv depending arm 55 engages the adjacent car- `riag'e l54, the `slots 57 of the carriages are vertically alined with the small spaces be-v to the .nature of the work. It will be noted that tween the friction wheels 58 and 59` so as l gagement of the pads 67 with the faces of 'the outer plates of the .pilesl of plates when the carriages 54v are fed toward said plates 6. v

- From the forging, a will be noted that' as the pilesof plates diminish the vcarriages 54 move .transversely of-thef tank l5in a direction'awayy vfromthe tinning pot sothat the padsYY 67 are maintained in1contact with the outermostjplates and wheuthis takes place' the shafts `29- and 34 move relative to the shaft' 22 and relativejto eachother away from the tinni'n pot and thelazy `tongs 47 equalize this re ativeY movement so as to maintainsubstantiallythe same' space betweenthe-shafts 26l and 30 as between the shafts V308.1111325. `l

As shown clearly in Fig. 3, the brackets 19 are connected by a transverse bar 75, while the shaft hangers 33 are connected by a similar bar 76 so that rigidity is insured and any movements of these parts must be in unison.

As shown clearly in Figs. 1, 8 and 9, the brackets 19 are provided with bearings 77 and 78 in which shafts 79 are 'ournaled and the latter of which is adjustable toward and from the bearings 77. LThe shafts 79are arranged between the shafts 14 and 22 directly above the {lux-box -9 and have suitable friction rollers 72 secured thereon in the same relation as has been described with respect to the rollers 27, etc. The shaft in the bearings 77 of the brackets 19 is provided with a sprocket chain connection 80 with thek shaft 22 whereby rotation of the friction rollers 72 is had, and intermeshing gears 81 'are provided between'the shafts in the bearings 77 and 78 and between shafts 22 and 26 as well as between shafts 29 and 3() and 34 and 35 whereby rotation of one of said shafts insures rotation of the other opposed thereto. In other words, each of the shafts 22, 29 and 34 are driven by the power shaft 11 and the rotation thereof is communicated to shafts 26, 30 and 35 by means of spur ear connections '81, while the shaft in the earings 77 is driven from shaft 22 by the chain gearing 80 and interl meshing spur ears 81 are also provided between'the sha ts in the bearings 77 and 78 whereby these two latter shafts are also driven in unison. I

The collars 42 of the frame members 40,

41, 43 and 44 open into the s1ots`16 so as to permit insertion of -the shafts.22, 26, 34 and 35 concentrically within said collars 42. The collars 42 are then slid and secured within the collars 42 through the use of a set screw or the like whereby said shafts are effectively removably held in operative position.' vThis provides for convenient assembling and disassembling of the parts and also allows rapid repairs. The gear connection between the vertical shaft 13 and one of the shafts 14 of the flux-box preferably com-prises a worm gearing as at 82" in Figs. 10 and 11, and, referrin to Figs. 16 and 17, it will be seen that t e ad 67 of each elevating device is provide with bolts 83 for reception of nuts 84 wherebysaid pads are fastened t'o the chains 64.

If desired, suitable brackets 85 may be attached to the flux-box ends so as to permit en a ement of hooks therewith whereby the hoisting mechanism 53 may be employed for removin said flux-box for repairs or the like. It is also noted that intermeshing gearing 81 is provided between the shafts 60 and 61 as shown clearly in Fig. 3 for insuring driving of these shafts in unison.

The slots 57 are varied in size for properly accommodating plates of varying thicknesses while insuring outward passage of only one plate at a time, by means of an adjustable plate 86 for each slot which is suitably mounted for sliding movement in a guide 87 and adjustable b`y a screw 88 as shown in Figs. 14 and 15.

In operation, the tins or plates are pass'ed upwardlyfrom the packs or piles singly' and successivelyto and between the rollers 58 and 59 by means of' the .elevating devices which include the p'adsV o r friction members 67. After a sheet or plate passes the rollers 58 and 59, it is deflected by the guides 46 between the rollers 36 andf37 of the elevated or overhead feeding mechanism to and between the rollers 31 and 32 of the latter and then to and between the rollers 33 and 27 from whence it is deliected downwardly by the guides 45 so as to pas's between the rollers 72 and 14 and through the guides 8 in the flux-box.
